Storage of the thermal energy is temporary storage of low or high heat energy for later use. Substances that can absorb heat during the transition from one phase to another or vice versa, can emit the stored heat during phase change, are called phase change materials. Phase change materials are also known as latent heat storage materials. Applications of the microcapsuls, which consist phase changed materials, to the textile products is the subject that has been dwelled on importantly in recent years.
In this study, single jersey knitted fabrics were produced from natural fibers by using the single plate of a double plate circular knitting machine. Paraffin-based phase change material was applied to the single jersey knitted fabrics by the impregnation method. The processes of squeezing, drying and then fixing were applied to the fabrics. The thermoregulation properties of the fabrics, whose physical properties were measured, were analyzed by differential scanning calorimetry (DSC), morphological properties were analyzed by scanning electron microscopy (SEM), and structural properties were analyed by Fourier Transform Infrared Spectrophotometer (FTIR). SEM, DSC and FTIR analyses were made to the PCM applied fabrics before and after home washing and the results were evaluated. The presence and distribution of microcapsules in fabrics before and after washing were investigated by scanning electron microscopy (SEM) analysis. For this purpose, SEM images were taken from the PCM applied samples before and after home washing. To determine the phase change material at the fabric structure, DSC analysis was performed to the fabrics which was after PCM application / without home washing and after home washing. FTIR analysis was performed using Fourier Transform Infrared Spectrophotometer (FTIR) device to chemically explain the presence of microcapsules in the fabric structure of microcapsule-applied fabrics.
